The edge of the reamer and drill bit can cut metal, one is only oriented, and why?
Reduce the cutting heat caused by friction during processing, prevent the bit and reamer from overheating and change the tool material, affecting the service life of the reamer and drill bit.

The edges of the two cutters can be used for micro cutting and scraping the walls of the extruded holes. The main cutting edges are end teeth (ends), but the main cutting edge of the reamer is small, the force is uniform, and the vibration is small. The drill main cutting edge cutting capacity, the cutting force is high, at the same time by centering the drill chisel edge effect, if the chisel edge center of bad point circle, the pore radius, the edge was just a guide.
